        A scatter graph. Used to represent many data points over a period of time. For example, events occurring in a given year.

        The example file is <a href="../examples/scatter.html">here</a>.

    <p>
        As you can see each mark on the Scatter chart is made by supplying an array of up to 4 elements:
    </p>
    
    <ul>
        <li>The X value (required)</li>
        <li>The Y value (required)</li>
        <li>The color (optional)</li>
        <li>The tooltip for this mark (optional)</li>
    </ul>
    
    <p>
        If you wish to specify a tooltip, but not a color (ie use the default color instead), you can pass null instead of a color.
    </p>


    <h2>Available properties</h2>
    
    <p>
        You can use these properties to control how the Scatter apears. You can set them by using the Set() method. Eg:
    </p>
    
    <p>
        <b>myScatter.Set('chart.xmax', 365);</b>

    <a name="boxplots"></a>
    <h4>Box plots</h4>
    
    <p>
        Instead of a single Y value, you have the ability to specify an array of 5, 6, 7 or 8 values, which will be used to make a box plot.
        The <a href="../examples/scatter.html#boxplots">example page shows a box plot</a>. These values are (in order):

        <ul>
            <li>Lower whisker</li>
            <li>Bottom of box</li>
            <li>Middle value (which isn't necessarily in the center of the box - this depends on your data)</li>
            <li>Top of box</li>
            <li>Upper whisker</li>
            <li>Upper color (optional)</li>
            <li>Lower color (optional)</li>
            <li>Width (optional)</li>
        </ul>

    <a name="labelpoints"></a>
    <h4>Specific points for labels on the X axis</h4>
    
    <p>
        Instead of a simple string which is used as the label, each entry of the chart.labels array can be a two element array
        consisting of the label, and the X value that the label should be placed at. For example:
    </p>

    <pre class="code">
scatter.Set('chart.labels', [
                             ['Quarter 1', 0],
                             ['Quarter 2', 90],
                             ['Quarter 3', 181],
                             ['Quarter 4', 273]
